Hi Folks ,
i get it !. New Day , New fresh Brain 
You have to mix the Main outs 1-2 to ADAT 1-2 and 5-6 and the 5-6 to the 3-4 and 7-8
simultaneously ! Thats all.
This routing is only checked with RME FF800 , don´t know the other Interfaces.
Be carefully with feedback while changing to 44,1 .Toggling between 96 and 44 changed the Input routings from RME Mixer Total Mix.
Example ADAT 17-18 in 96 was 21-22 in 44,1 so in Logic I/O Instruments you have to check the Buss Routings !
